Same thing, I had the problem with 4.4.x, upgraded to 4.5.1 and still the same thing. The splash and welcome screen render then everything disappears with the following error:
The program 'kdevelop' received an X Window System error. This probably reflects a bug in the program. The error was 'BadWindow (invalid Window parameter)'. (Details: serial 2215 error_code 3 request_code 20 minor_code 0) sudo is not really a viable workaround... :( -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1178843 Title: kdevelop won't start To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/kdevelop/+bug/1178843/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
